Availability check for a ware

Abstract

Computer-implemented methods, and associated computer program products and systems, for checking availability of a ware in a time interval, a resource to produce the ware being associated with the ware. The computer-implemented method can include obtaining capacity supply information comprising a capacity supply for each date of the time interval and capacity demand information comprising a capacity demand for each date of the time interval. The first date of the time interval is set to a later date, there is determined for each date from the first date to the later date whether capacity supply is unused. If capacity supply is unused, the method includes eliminating the specific amount from the capacity supply information. In response to demand information representing a demand having a requested date, availability of the resource on the requested date is determined using the capacity supply information and the capacity demand information.

1. A computer-implemented method for checking availability of a ware in a time interval, a resource to produce the ware being associated with the ware, the method comprising:
 obtaining, by a computer system, capacity supply information of the resource comprising a capacity supply for each date of the time interval, wherein the time interval comprises a plurality of dates, 
 obtaining, by the computer system, capacity demand information for the resource comprising a capacity demand for each date of the time interval, 
 in response to receiving an update information indicating that a first date of the time interval has been set to a later date, for each date from the first date to the later date in chronological order:
 designating, for production by the resource on each date from the first date to the later date, production orders that have been released by each date until either i) the resource has no remaining capacity supply on each date or ii) all of the productions orders that have been released by each date have been designated, 
 determining, by the computer system, whether the resource has capacity supply on each date from the first date to the later date that is unused after the designating, and 
 if a specific amount of capacity supply is unused for each date from the first date to the later date, eliminating the specific amount of capacity supply from the capacity supply information to generate modified capacity supply information for the resource, and 
 in response to receiving a demand information representing a demand having a requested date, determining availability of the resource on the requested date using the modified capacity supply information and the capacity demand information. 
 
 
     
     
       2. The method of  claim 1 , wherein the capacity supply and the capacity demand is each cumulated starting from a first date of the time interval. 
     
     
       3. The method of  claim 1 , wherein obtaining the capacity supply information comprises defining a capacity constraint of the resource. 
     
     
       4. The method of  claim 1 , wherein obtaining the capacity supply information comprises defining a capacity load of the resource for a unit of the ware. 
     
     
       5. The method of  claim 1 , wherein determining for a specific date whether capacity supply is unused comprises obtaining an amount of used capacity of the resource, used to produce ware on the specific date. 
     
     
       6. The method of  claim 5 , wherein a specific amount of capacity supply is unused, provided that the capacity supply on the specific date is greater than the amount of used capacity supply of the resource on the specific date. 
     
     
       7. The method of  claim 6 , wherein the amount of used capacity supply of the resource is associated with a production order of the ware. 
     
     
       8. The method of  claim 1 , wherein the resource is used to produce at least one other ware. 
     
     
       9. The method of  claim 1 , wherein at least one other resource is associated with the ware. 
     
     
       10. The method of  claim 1 , wherein the resource is a bottleneck resource. 
     
     
       11. The method of  claim 1 , wherein the update information indicates i) that time has passed since the time interval for the capacity supply information was defined, ii) that the first date is a past date, and iii) that the later date is a current date. 
     
     
       12. The method of  claim 11 , wherein the specific amount of capacity supply corresponds to unused capacity as of the current date that is lost and no longer usable. 
     
     
       13. A computer program product tangibly embodied in a computer-readable storage medium and comprising executable instructions that, when executed, perform operations for checking availability of a ware in a time interval, a resource to produce the ware being associated with the ware, the operations comprising:
 obtaining capacity supply information of the resource comprising a capacity supply for each date of the time interval, wherein the time interval comprises a plurality of dates, 
 obtaining capacity demand information for the resource comprising a capacity supply for each date of the time interval, 
 obtaining a capacity demand information for the resource comprising a capacity demand for each date of the time interval, 
 in response to receiving an update information indicating that a first date of the time interval has been set to a later date, for each date from the first date to the later date in chronological order: 
 designating, for production by the resource on each date from the first date to the later date, production orders that have been released by the date until either i) the resource has no remaining capacity supply on each date or ii) all of the productions orders that have been released by each date have been designated,
 determining, by the computer system, whether the resource has capacity supply on each date from the first date to the later date that is unused after the designating, and 
 if a specific amount of capacity supply is unused for each date from the first date to the later date, eliminating the specific amount of capacity supply from the capacity supply information to generate modified capacity supply information for the resource, and 
 
 in response to receiving a demand information representing a demand having a requested date, determining availability of the resource on the requested date using the modified capacity supply information and the capacity demand information.
